The wait is over, Avatar fans, as we've got a first trailer for Avatar: Fire and Ash, which is the third movie in James Cameron's sci-fi franchise and is set to be one of this year's biggest new movies.

We see two new Na'vi tribes in the trailer: the Wind Traders and the Ash People clan, the latter of whom seem to represent most of the menace in the film. We see the Ash People using fire as a weapon, with one of the aliens even seeming to be able to wield it on her bare hands without hurting herself.
